Abstract
The utility model discloses a hole-blanching device for cylindrical battery core, which is realized by adopting the technical scheme that an electric heating wire is internally arranged in a through-hole needle, and is connected with a power supply, the tail end of the through-hole needle is fixed in a holder, and a temperature detector is arranged in the holder. The temperature detector is connected with a temperature control switch and a temperature controller in turn, and the holder is arranged in a casing. The hole-blanching device is applied, which not only reduces through-holes and the fraction defective of welding process, saves cost, but also avoids the problems of inner short-circuit and battery heating caused by the damage of a center hole diaphragm, reduces the potential safety dangers of the battery, and increases the safety of the battery.
Description
Technical field
The utility model relates to cylindrical battery electricity core central hole barrier film modular system, more particularly, relates to a kind of blanching aperture apparatus that is used for cylindrical battery electricity core.
Background technology
For cylindrical battery in process of production, in electric core that coiling is finished and the battery case back welding termination process, capillary need pass through centre bore, also need as required in addition in the battery centre bore, to insert draw point, so need the battery that coiling is finished is carried out the reaming processing, with expansion of the barrier film in the centre bore and typing, to guarantee in the weldering end and insertion draw point, the barrier film in the centre bore can not destroyed, cause the internal resistance short circuit.At present domestic manufacturer is in the production process of this operation, draw point pressure cold expansion method is all adopted in the central hole reaming, centre bore barrier film after this kind method expansion easily rebounds, and in subsequent production, causes easily that centre bore destroys to cause potential safety hazard and tremendous loss.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of blanching aperture apparatus that is used for cylindrical battery electricity core is provided.
The utility model is used for the blanching aperture apparatus of cylindrical battery electricity core, is achieved by following technical proposals, and through hole pin in-built electrical heater strip, electrical heating wire is connected with power supply; Through hole backshank end is fixed in the holder, in the described holder hygrosensor is set; Described hygrosensor connects temp control switch and temperature controller successively; Described holder is arranged in the sleeve pipe.
The utility model through hole pin diameter and battery battery core aperture coupling.
The utility model content is that the mode according to the expansion of the characteristic of battery battery core diaphragm material and centre bore designs, designed the through hole pin that can heat, and can the temperature of through hole pin be control effectively, mode by heating makes the barrier film expansion, naturally typing after cooling, and heating-up temperature is no more than the barrier film melt temperature, can effectively play the effect of reaming, avoids centre bore bounce-back and barrier film to be destroyed simultaneously.
By using the utility model, can effectively solve the battery centre bore and expand problems such as bad and barrier film bounce-back, can effectively avoid simultaneously stabbing at the centre bore that weldering basic skill or training preface causes, the barrier film breakage causes a series of problems such as internal short-circuit, not only reduce through hole and welding process fraction defective, save cost, can avoid simultaneously because internal short-circuit and the battery heating problem that the breakage of centre bore barrier film causes, reduced the potential security risk of battery, the fail safe that has improved battery.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, through hole pin 1 in-built electrical heater strip 2, electrical heating wire is connected with power supply; Through hole backshank end is fixed in the holder 3, and hygrosensor 4 is set in the described holder; Described hygrosensor connects temp control switch and temperature controller successively; Described holder is arranged in the sleeve pipe 5.
The said fixing seat in order to the fixed via pin, and connects hygrosensor; Hygrosensor is connected with temp control switch, and the temperature that detects is transferred to temperature controller, is sent the instruction that continues heating or stop to heat by temperature controller; Holder is arranged in the sleeve pipe, and sleeve pipe is used for fixing the through hole pin, and uses for when operation as handle; Temperature controller receives the information that temp probe is passed back.
The utility model passes through Precision Machining, in thinner pin, added electrical heating wire in order to give the heating of through hole pin, by thermocouple temperature information is passed to temperature controller simultaneously, send the instruction that continues heating or stop to heat according to the information of passing back by it, thereby effectively the pin temperature is scalded in control, keeps scalding the pin temperature constant, promptly reaches the effect of heating barrier film typing, can avoid the too high destruction of causing barrier film and electric core of temperature again, thereby reach the design effect of expection.
Example recited above only is that the utility model preferred implementation is described; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection range of the present utility model.
